LUBRIGANT DISPENSER Filed April. 23. 1928 Patented Get. 20, 19317 i HERMAN PErERleaossMAN,on-,iaoonvrnnmrumana LUBRICAN T DISPENSER Application led Apri1'23,

My object is to provide an improved pressure-feed can adapted for holding and for feeding in any desired quantity light or heavy oils and greases at temperatures ranging 5 downward'to relatively low points, regardless of the angle or position assumed byY the can.

The invention embodies a canfor receptacle having caps for its ends, a piston or plunger in contained within the receptacle, a feed-screw having a screw-threaded engagement with the plunger, and an operating handle or handwheel carried by the feed-screw and engaged with one of said caps, combined inan improved manner, the-can being provided, if desired, with a spout and a handle. In lieu of the spout, the feed-screw maybe hollow and serve as a spout. The manipulating'handle for the can may be arranged as shown in the drawings, or, otherwise, dispensed with, as may be preferred.

In the accompanying drawings:

Figure 1 is a side elevation, partly in section; and n 1 Fig. 2 is a cross-section on the line 2-2, Fig. 1.

The shell or can 1 is provided with caps`2 and 3, either or both of which maybe removableAs shown, the cap 3 is removably connected to thershell 1 by screw threads l. The cap 2 may be similarly detachably Vconnected to the shell 1. As shown, said cap 2 is provided with a handle attached thereto at 6 and either attached to, or looselybear- '35 ing against, the shell 1 at 7. l l Y Any suitable spout Aor nozzleS is detachably connected, asby anipple 9, to the capV 2. Inside of the shell 1 is a piston or plunger 10 whose periphery is provided with a leather, or other suitable .cup or packing 11 which packs7 theplunger and Vprevents i escape of the lubricant past it. Y

The plunger is fed by a screw 12 which has a screw-threaded engagement with a hole 13 in said plunger. The screw 12 has a suitable 1928. seriaino. 272,307.

hand-wheel 13 fastened to its upperend, the

Vhub of said hand-wheel bearing on a suitthrough spout 8 in either drop-like', or,- eX- truded consistency, according to the nature of the lubricant, itstemperature, and the manner in which the hand-wheel 13 is operated..

If the s crewy 12 be hollow the spout 8 and nipple 9 will be omitted andthe lubricant, which will be located below the plungergwill be delivered through a spout, kor otherwise, from the upperend of the hollow screw 12. v

The handle 5 Vcan bey wholly carried by the shell 1 if desired.

' Regardless of temperature, down near l the freezing point, any lubricant can be ydispensed because the pressure available by the i use of the feed-screw is capable of effecting dispensing the lubricant whether it is soft or relatively hard. What I claim is: *f

' 1..In a lubricantdispenser, the combinationwith a lubricantcont'ainer, of a plunger f therein, a cap detachably connected to the container, said ycap completely closing the end of the container, al hollow feed screw formoving said plunger 'within the container,

said hollow feed screw being carried by the cap and serving the double purpose of feed- Ving said'plunger to exert pressure upon the lubricant and as a conduit for delivering the lubricant from the container lwhen said feed screw is turned, means on the cap for pre- .Y venting the yfeed screw from shifting length- Wise when turning, and a hand Wheel carried by said feed screw outside of the container and bearing on said cap, whereby said feed Y screw may be rotated, and a removable cap at4 the end of the container opposite the cap firstnamed, said cap completely closing that end of the container.

In a, lubricant dispenser, the' combina-V tion with a lubricant container, of a removable cap therefor, a single loop-shaped handle having its upper end permanently at# taohed to Vsaid cap so as to be bodily removable therewith and its loyverend adapted to bear on the side of the Container in a free'nannel-L In testimony whereof I affix my signature.
